| Can SMPS based preamps/amps sound organic ? SMPS issues got sorted out a long time (decades) ago. These days a properly designed SMPS should be as quiet or quieter than a conventional supply. | |
| Direction of aftermarket fuses (only for believers!) just to set the record straight, UL is not a requirement or a directive, it’s a guideline or standard.I did not state that it was. I did state that the CE mark was a directive, and that there are others. You simply chose to misinterpret, as part o... | |
| Direction of aftermarket fuses (only for believers!) I read your last post. I read your last two posts. Did I err? Did I misinterpret something? As far as I can tell, you misinterpret on purpose. That makes it hard to have a conversation. Example: Or maybe you’re insinuating that any person who does... | |
| Electrical issues with Philips GA 212 Electronic Ken's comments above are exactly spot on. I think you might have some success retrofitting an LED for the job- that way you can set the current (by bypassing the LED with a resistor) such that the unit will work without your finger on the sensor. | |
| Direction of aftermarket fuses (only for believers!) I meant if you wanted to get to the truth you would eliminate the fuse holder from the equation. You know, for the experiment. Capish? Whether or not aftermarket fuses meet UL, etc. is irrelevant to the question of directionality. You don’t rea... | |
| Atma-sphere amps best power tubes @don_c55 , he did that about a year ago. | |
| Direction of aftermarket fuses (only for believers!) Al, if you (and Atmasphere) really were thorough you would simply eliminate the fuse holder entirely, no?No. That would never meet UL, CE or other directives. | |
| Direction of aftermarket fuses (only for believers!) If y'all are interested, I think I've sorted out what this reversal phenomena is all about.It has to do with the fact that the connections on fuse holders are not perfect. The act of reversing the fuse sometimes gets you a better connection. Howev... | |
| I'm happy but I want more, more, more Sadly we are not all millionaires and the best analogue is rapidly becoming a rich man's hobby I see people putting together very successful systems using modest equipment like the Technics SL1200 with a Grado Gold cartridge, amps like a Dynaco S... | |
| Why does my 35 watt tube amp draw 300 watts of power Tube amps are only 5% efficient. We can easily see from the opening post of this thread that the above statement is false. If you can get two channels of 35 watts from 300 watts of wall power, clearly the amp must be more like 20% efficient, in th... | |
| I'm happy but I want more, more, more With electronics it seems to pay best if you start the upgrades upstream and work your way downstream to the amp and speakers. No matter how good your amps and speakers are, they can't recover information lost by the front end. So you get that rig... | |
| Weird Popping issue It does sound like a power tube; a power tube failure would reduce output, but not kill it entirely. | |
| Buzzing noise. It is normal for a buzz to result if the amp is on and connected to a preamp which is off.The preamp of course should be turned on first, this to avoid damaging the loudspeakers should there be a turn-on thump.If the buzz is then so quiet as to on... | |
| Weird Popping issue If you have a Primaluna I would start with Kevin at Upscale Audio.You might also look on ebay- that can be a good source if you know what you are looking for. Also try CE Distrubution in Arizona. Of course, a lot depends on what tube type it is an... | |
| Weird Popping issue The chances that this is a bad tube are pretty high. My guess is it will be one of the smaller tubes- not one of the power tubes. The tube is likely developing a cathode/filament short or similar. Quite often the short will heal temporarily if the... |
